PATENT GUSTAV A. BISLER, OF PHILADELPHIA, PENNSYLVANIA.

FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 763,142, dated J une21,v 1904.

Application tiled November 14, 1903. Serial No. 181.183. (No model.)

Tr; nel] 11:/1/0711, t may concern.'

Beit known that I, GUsTAv A. Bisnnr., a citi- Zen of the United States,residing' in the city and county of Philadelphia, State of Pennsylvania,have invented new and useful Improvements in Folding Boxes, of which thefollowing' is a specification.

My invention consists of an improvement in a folding box, as will behereinafter described, and pointed out in the claim.

Figure l represents a perspective view of a folding' box embodying` myinvention, one end of which being shown closed and the other end opened.Fig. 2 represents a section of a portion on line f1; a', Fig'. 1. Fig. 3represents a vertical section of the complete box. Fig. e represents avertical section of a portion on an enlarged scale. Fig. 5 represents aperspective View of the body of the box in folded condition. Fig. 6represents a vertical section of a portion of the box in foldedcondition on an enlarged scale. Fig'. '7 represents a vertical sectionof a portion of the lid of the box.

Similar letters of reference indicate correthe exterior of the end foldsD are the staples F, and in the flaps E are openings G, which areadapted to receive said staples F. Then the parts of the box are inassembled operative position, said staples protrude sufficiently to havestraps H pass therethrough, said straps being' connected with the endfolds D and appear on the exterior thereof, said straps and staples thusconnecting the adjacent end folds and flaps and retaining thefsame inthe upright position of the box. Vhen the lid J is placed on the body ofthe box, the ends of the straps H are connected by the strap K, thelatter extending above the lid J and forming a convenient handle for thebox and serving to retain the lid in position.

L designates the creased lines between the bottom B and sides C, and Mdesignates the creased lines between the bottom B and end folds D, itbeing noticed that each of said creased lines is formed by compressing'the material of the body of the box along the lines of the creases so asto upset said material, whereby the latter appears on one side as agroove and the other side as a bead, without fracturing the material orinjuring the fiber' thereof and in other respects forming a well-definedjoint of the order of a hinge which permits of ready folding andunfolding' of the sides, end folds, and flaps and also preserving thestrength of the box at the respective creases. On the end folds D arecreases Y, which extend parallel with the creases M and are adjacentthereto, it being noticed that the material existing between the creasesM and N forms additional folds or walls P, which subsequently occupy theends of the box when in folded condition, as will be hereinafter morefully explained. As the tendency of the additional walls P is to drop,and thus lower the end folds D, the flaps E on the sides C serve toAbrace and hold up said end folds, and then as said iaps and end foldsare coupled bythe staples F and straps H, said staples passing throughthe openings G in said fiaps, as has been stated, the contiguous flaps,end folds, and additional walls are connected as one, thus vastlystiifening the ends of the box.

In order to fold the box, the handle-strap K is removed and the straps Hwithdrawn from the staples F. The flaps E are then folded upon the sidesC and said sides C and flaps E folded on each other on the bottom B.Then the end folds D are folded inwardly over the sides C, it beingnoticed that said folds turn on the creases M as their hinges, bringingthe folds P at the ends of the sides C and flaps E. Then said folds Dare folded downwardly on the sides C and turned on the creases N astheir hinges, the folds P permitting' the folding of the end folds Dflat on the sides C regardless of the several thicknesses of materialbetween the bottom B and the end folds D without straining the creases Mand N and without fraeturing or cracking of the side creases M N andfolds P, as willbe apparent in Fig'. 6. The box in its folded conditionIOO appears as in Fig. 5, when, if desired, the straps H may passthrough the staples F, thus preventing opening of the parts, and thebody may be placed in the lid J with the l1andlestrap therein, formingconvenient package for carrying, packing', transportation, &e., or thebody of the box may be liattened out in linoclzdown condition, ifdesired.

Various changes may be made in the details of construction shown withoutdeparting 'from the general spirit of my invention, and l do not,therefore, desire to be limited in each case to the saine.

Having thus described my invention, what C. D. MCVAY, S. R. CARR.
